We posit that to achieve superhuman agents, future models require superhuman
feedback in order to provide an adequate training signal. Current approaches
commonly train reward models from human preferences, which may then be
bottlenecked by human performance level, and secondly these separate frozen
reward models cannot then learn to improve during LLM training. In this work,
we study Self-Rewarding Language Models, where the language model itself is
used via LLM-as-a-Judge prompting to provide its own rewards during training.
We show that during Iterative DPO training that not only does instruction
following ability improve, but also the ability to provide high-quality rewards
to itself. Fine-tuning Llama 2 70B on three iterations of our approach yields a
model that outperforms many existing systems on the AlpacaEval 2.0 leaderboard,
including Claude 2, Gemini Pro, and GPT-4 0613. While only a preliminary study,
this work opens the door to the possibility of models that can continually
improve in both axes.

通过自我奖励语言模型的迭代 DPO 训练，本研究展示了模型的指示遵循能力及为自身提供高质量奖励的能力的提升，最终的 Llama 2 70B 模型在 AlpacaEval 2.0 排行榜上表现优于许多现有系统，包括 Claude 2、Gemini Pro 和 GPT-4 0613。这项初步研究为模型在两个方向上不断改进的可能性打开了大门。
